You might think that {{t|Nẻo tu bỉo sa tỏqfua}} means "every cup is on ''some'' table", where possibly each cup is on its own table. Certainly, presenting sentences such as <math>\forall b, \exists t: N(b,t)</math> is popular in discussions of predicate logic. | You might think that {{t|Nẻo tu bỉo sa tỏqfua}} means "every cup is on ''some'' table", where possibly each cup is on its own table. Certainly, presenting sentences such as <math>\forall b, \exists t: N(b,t)</math> and assigning them this interpretation is popular in discussions of ''singular'' predicate logic. | ||
But because the plural-logic {{t|tu bỉo}} ranges over all "cups-es", i.e. all groups of cups, it also includes the referent "{{t|bío}} = ''all'' relevant cups together". Consequently, this sentence ends up saying that all cups are on the ''same'' table, namely whichever {{t|sa tỏqfua}} this maximal {{t|bío}} is on. | But because the plural-logic {{t|tu bỉo}} ranges over all "cups-es", i.e. all groups of cups, it also includes the referent "{{t|bío}} = ''all'' relevant cups together".
